In 2010 Maxim acquired Teridian Semiconductor to create a device portfolio for Smart Metering applications. Recently a new device was added, the 78M6631, which is a highly integrated three-phase power measurement and monitoring system-on-chip (SoC) with a 10 MHz 8051-compatible processor core. Designed for a wide variety of applications requiring three-phase power and quality measurements, it is available with preloaded firmware that supports both delta and wye (Y or star) three-phase configurations.
